Another Rover to Mars?

NASA plans to send a new rover to Mars in 2020 as it prepares for a manned mission to the Red Planet. This announcement came a day after NASA released the results of the first soil tested by the Curiosity rover. Traces of some of the compounds like water and oxygen that are necessary for life were found. President Barack Obama's administration "is committed to a robust Mars exploration program”, NASA Administrator Charles Bolden said in a statement. The design of the new rover will be based on Curiosity in order to cut costs and reduce risks of engineering errors.
